FYI, we have just switched the gerrit e-mail notifications from this list to a new gerrit-log@lists.osmocom.org mailing list, which can be found at https://lists.osmocom.org/mailman/listinfo/gerrit-log
So if you want tho subscribe to the notifications, feel free to subscribe to that separate list. If not, simply stay on the project lists (openbsc@lists.osmocom.org, osmo-net-gprs@lists.osmocom.org) and you will not see any such auto-generated mails anymore.
Sorry for any inconvenience caused.
Regards, Harald
